Factors Affecting the Dry Quenching of Coke SpringerLink

2019-10-23  Abstract. The basic factors that affect the efficiency of dry-quenching systems at coke plants are identified by numerical modeling. On the basis of quantitative estimates, recommendations for increasing the efficiency of coke cooling are made. Giprokoks dry-quenching systems operate successfully at numerous coke plants.

New Development in the Dry Quenching of Coke

2019-5-8  In low-intensity dry-quenching systems, the same effect is compensated by increase in the volume of coke blowed with gas (thanks to increase in diameter of the quenching chamber) and by optimizing the intake distribution system, with decrease in the gas flow rate to 1.2–1.4 m 3 /kg and decrease in the coefficient taking account of the ...

Improving the quality of dry-quenched coke SpringerLink

2015-9-12  Existing approaches to improving the quality of dry-quenched coke are appraised. The influence of the composition of the circulating gas on the quality of the cooled coke in the dry-quenching system is investigated. The composition of the circulating gas (its CO and CO2 content) is found to significantly affect the ash content in metallurgical coke and also the reactivity CRI and strength CSR ...

2017-6-3  In assessing the operational efficiency of dry-quenching units at coke plants, it is important to consider the coke losses. In the present work, existing methods of determining the coke losses are analyzed. The method selected is based on continuous measurement of the flow rate and composition of the excess circulating gas released from the dry-quenching unit; it is compatible with different ...

2015-3-21  The physicochemical and thermal properties of coke dust formed in the dry-quenching process are studied, with a view to its use in pulverized-coal fuel for blast furnaces. The use of such dry-quenching dust in pulverized fuel is complicated by three main factors: its elevated ignition temperature; low chemical activity; and highly abrasive properties. Differential scanning calorimetry is used ...
